I have found it to be quite nice. You still can get certain kinds of calls and businesses consider the little "Contact Me" button at the bottom of surveys or when you sign up for membership at Amazon or some crap to be a "solicitation" of a call.

So, you just have to be aware of that stuff. I was averaging two or three telemarketing calls a day and now average one or two a week.

I know that the brokerage that my company partners with has a machine that limits the cold call numbers from the DNC list and that it's updated regularly. So I can't speak for everyone, but as for SEC and NASD related companies, it's not a option, it's the law.
